New Delhi, Oct 21 2007 : Pradeep Sarkar's latest Laaga Chunari Mein Daag is probably the most well etched sisterly act ever in Indian celluloid. And that brings us to the real life sister duos of Bollywood. Beauty, blood and Bollywood bind them. Similar, yet distinct. Probably, the first pair of sisters, who made an impact on the silver screen, was Nutan and her sister Tanuja, who continues to do character roles even today. And so followed the others. So thumbs up to these awesome twosomes!
